R-1234yf Regas and Repairs

Car manufacturers are being forced to change the refrigerant used in the air conditioning system over the next few years from R134a to r1234yf. The motor industry has decided that the refrigerant used for the past 20 years is less environmentally friendly than a refrigerant with a lower Global Warming Potential (GWP).

R-1234yf Refrigerant behavior is very similar to R134a, which allows component manufacturers as well as automotive designers the luxury of not having to make drastic changes to current products.
